SRBL is an automated, ground-based instrument developed
at Caltech and currently operated by the NJIT Center for Solar-Terrestrial
Research. The instrument acquires microwave spectra of solar activity
throughout the observing day and locates large bursts on the sun using
a single radio dish. Shown below is the latest two hours of data taken
by a prototype at the Owens Valley Radio Observatory, updated every 10
minutes.
